Abstract: A method and an apparatus for producing concrete articles, such as shaft rings, with projecting elements such as climbing irons or stirrups, by means of an automatic inserting mechanism which removes the climbing irons from a magazine and automatically inserts them into a mold core. These climbing elements are guided automatically to a core segment and are brought into housings therein during a time interval between the ejection of a completed concrete article from the mold cavity in a first working cycle and the next following work cycle in timed overlap with carried out work steps during this time interval. This automatic process takes place while the operator withdraws and takes away a completed article from the machine at the end of a work cycle and prepares the machine for the next work cycle. This leads to equally short machine cycle times for completion of concrete articles with or without climbing elements.

Abstract: A personnel dosimeter includes a plurality of compartments containing thermoluminescent dosimeter phosphors for registering radiation dose absorbed in the wearer's sensitive skin layer and for registering more deeply penetrating radiation. Two of the phosphor compartments communicate with thin windows of different thicknesses to obtain a ratio of shallowly penetrating radiation, e.g. beta. A third phosphor is disposed within a compartment communicating with a window of substantially greater thickness than the windows of the first two compartments for estimating the more deeply penetrating radiation dose. By selecting certain phosphors that are insensitive to neutrons and by loading the holder material with neutron-absorbing elements, energetic neutron dose can be estimated separately from other radiation dose. This invention also involves a method of injection molding of dosimeter holders with thin windows of consistent thickness at the corresponding compartments of different holders.

Abstract: A technique for the rotational molding of hollow articles having separate but structurally integral compartments is described. A mold in which the article is to be formed is provided with a cover between the mold cavities in which the article compartments are to be rotationally molded.
